Can't Enable Secure Boot on MSI Laptop

Sorry if my explanations are unclear, I'm not the most tech-savvy person around. I own an MSI GF65 Thin 10SDR laptop, and I've been having trouble enabling Secure Boot on it. I've gone through days of troubleshooting and trying to find solutions. The main problem is that I cannot disable CSM in the BIOS and enable secure boot without causing a "Secure Boot Violation, Invalid Signature Detected" error. The laptop is running Windows 11, so Windows WHQL support isn't available. I also updated my BIOS just today, incase it would help, and it did not. I've tried resetting BIOS firmware keys, enabling CSM and running secure boot on top (which disables it, unsurprisingly).. pretty much everything I could find online. Any help is appreciated.
